Collapsible labyrinth

Abstract

A collapsible labyrinth is constructed with a plurality of collapsible separating boards temporarily secured by vertical pivotal posts, two horizontal bars respectively on and under a line of separating boards to secure upper and lower ends of the pivotal posts, and tenons fitting in a mortise in a lower end of each separating board and also in one of tenon holes preset in the ground for securing temporatily each separating board so that the boards can be altered in position to make up a labyrinth route.

What is claimed is: 
     
       1. A reconfigurable amusement labyrinth system comprising: (a) a plurality of collapsible wall members, each of said collapsible wall members having at least a first wall section, at least a second wall section, and an elongated securing post having a cylindrical contour, each of said first and second wall sections having opposing sides forming a first surface and a second surface defining a thickness dimension, each of said first and second surfaces forming a planar contour extending in a longitudinal direction, said first wall section having a longitudinally extended first coupling edge having formed thereon a plurality of planar projections projecting substantially orthogonal to said longitudinal direction, said second wall section having a longitudinally extended second coupling edge having formed thereon a plurality of planar projections projecting substantially orthogonal to said longitudinal direction for insert between planar projections of said first coupling edge for releasable coupling therewith, said planar projections of each of said first and second coupling edges having longitudinally aligned openings for passage therethrough of said securing post, each of said first and second wall sections having a bottom edge which has formed therein a mortise cavity extending in a longitudinally upward direction, each of said first and second wall sections having formed therein a longitudinally extended first handle slot formed into said first surface adjacent said mortise cavity of said bottom edge;   (b) a plurality of securing tenon assemblies, each of said securing tenon assemblies having an inverted U-shaped support member for insert into said mortise cavity of said bottom edge of either of said first or second wall sections, a longitudinally extended spring biased support peg member captured within said support member for insert into a support cavity formed in a ground surface, and a release handle for said support peg member, said support member having formed therein a longitudinally extended second handle slot, said support member being inserted into said mortise cavity of said bottom edge of either first or second wall section whereby said second handle slot is substantially aligned with said first handle lot of said first surface of either said first or second wall section, said release handle being inserted through both said first and second handle slots and affixed to said support peg member; and,   (c) a plurality of locking bars for aligning and transversely locking together a plurality of said securing posts of said collapsible wall members, each of said locking bars being elongated and releasably coupled to a first end of at least two of said securing posts.
